The defect
Gillig LLC (Gillig) is recalling certain 2018-2020 Low Floor transit buses powered by compressed natural gas (CNG). The thermally activated pressure relief device (PRD) installed on the CNG fuel system may not vent the system when exposed to heat, potentially resulting in the system rupturing.
The risk
If the fuel system ruptures from exposure to heat, there may be an increased risk of injury.
